The Let's Play Minecraft series is a weekly series consisting of five Achievement Hunter members; Jack, Geoff, Michael, Gavin and Ray. The series later expanded to include Ryan, who became a regular, and occasionally Caleb would join in and most of the time be a medium between community members and the AH team when playing on a community made map. Primarily, they use the Xbox 360 edition of Minecraft, with each episode usually being thirty to forty minutes long sometimes expanding into 2-part or 3-part episodes. The first episode was released on May 11, 2012, two days after Minecraft was released on the Xbox 360. The series reached it's 50th episode on May 10, 2013, one day before the anniversary of the series. The 100th episode was released on April 25, 2014, two weeks before the 2-year anniversary of the series, which featured a scavenger hunt that allowed the lads to re-visit some of the Let's Plays and Things To Do In structures that they did or built in the past 100 episodes. The 150th episode, according to calendar dates, is expected for release in April 2015, while the 200th episode, according to calendar dates, is expected for release in early April 2016.
During the first few episodes, the five of them only explored the world and 'griefed' each other. This includes killing each other, destroying each others houses, and accidentally getting lost or misplacing blocks in a hilarious fashion. In later episodes, the series started to focus primarily on goal/competition based gameplay, with a number of activities based around popular PC-version variants such as Hunger Games, parkour, and The Walls. The prize for winning a competition is a tower of four gold blocks known as the Tower of Pimps, which the member of the team pride themselves upon winning.
In Episode 67, the Achievement Hunters explored the world of the Mass Effect Mash-Up, which was the newest texture pack for Minecraft. At the end, they explored Achievement City using the Mass Effect Mash-Up Pack. During the video, the lads stated that they would explore the world of every new texture pack from now on. They explored the world of the Skyrim Mash-Up in Episode 82, but did not explore Achievement City with the Skyrim Mash-Up Pack.
Each of the members have a role/quirk that defines their behavior in the series and associated skin:
- Geoff's character skin is Master Chief from the video game franchise Halo, and is also a reference to his voicing of Grif in the Red vs Blue series. In Episode 106 his character skin was updated to the newer version of Master Chief, featuring more 3-dimensional features, though he's shown to switch between the old and the new skin. He is considered the leader of the group; organizing the team and dictating the way the competitions are run. He along with Gavin, are the main builders of most of the structures within Achievement City. Geoff has participated with the team during the early episodes of the series for the prized Tower of Pimps, but during the Dig Dug challenge he stated that he just likes to create more then competing and as a result has lead or filmed games than playing them. He is generally very competitive and will try to stack odds in his favor. For example, one of Geoff's Tower of Pimps wins had him build a sky fortress surrounded by lava and use diamond equipment. His house was built to jokingly represent his ego and Michael described it as a 'Monolith'. Due to the latest Minecraft patch adjusting the build height, Geoff and Gavin stated that Geoff's house is now even taller than before. As of the 2014 Achievement City tour video, Geoff's house is now at maximum build height. Inside his house he has a water ceiling at the former max height, this being first shown in the Things To Do In... episode, Indoor Pool. He also has a small raised platform representing a 'second floor' and a basement, dubbed "The Vault" that houses materials that can be used during play if they are not on Creative Mode. After Ray's departure from Achievement Hunter, a small shrine was made for him inside as well.
- Jack's character skin is the biker from the video game Trials HD. He is seen as a very slow and methodical player who examines every detail, which Geoff is known to exploit. During the earlier episodes he is shown to be very knowledgeable about Minecraft; dealing with lava and how to build a Nether portal. Many times after being stopped from winning a competition he would remark about "building a house", which became a common theme through non-competition related episodes. Early in the series, during episodes when Geoff is explaining, he would occupy himself with the cursor, pretending it was a butterfly. His house is a wooden house on stilts with a mine leading to the underground of Achievement City, with a lava ceiling made by Geoff. Later on, whilst he was out of town, a giant replica of Jack's character was made behind his house by Geoff, Gavin, and Ryan. The statue has an overhanging wool penis over top his house which can dispense water, or lava, with a switch below. As part of a failed prank, Jack's house was completely encased with obsidian. However due to Minecraft continuously crashing due to the waterfall prank on Gavin's house, his house was eventually uncovered with only a giant halo above his house remaining. Jeremy later on added a propeller cap to Jack's statue.
- Michael's character skin is Banjo from the video game Banjo Kazooie. Michael updated his skin to the new Banjo skin in Episode 106 with the new skin having more 3-dimensional features including a small Kazooie sticking out of his backpack, though he frequently switches between the old skin and the new. At first, Michael's defining quirk was that he didn't know how to play, often making mistakes, dropping pieces of equipment, and swearing a lot, reflecting his Rage Quit persona. Since then he has begun to understand the game more and the team refers to him as "Mogar" which he coined himself. He is generally aggressive towards other players; especially Gavin for his stupidity. He is an excellent fighter; winning multiple fighting related challenges, and generally being known for his fighting and hunting abilities. His house is a small wooden house that he shares his real life wife, Lindsay, with a secret underground room for Kerry and a tunnel that leads to Gavin's house.
- Gavin's character skin is a Creeper, which since the new update has often caused him to be mistaken for an actual Creeper. He constantly harasses and ridicules other players and as a result he is frequently the target of the other players' rage, even to the point where they'll physically attack him. He is also well known for griefing others' structures, usually leading to hysterical rages. His most well known exploits was pouring lava over the house during the first episode and co-creating Plan G. Despite being one of the only two members (the other being Ray) to have played the game prior to the original Let's Play, he often fails at what he does because of his own actions. Gavin is the co-creator of most structures in Achievement City and had also inadvertently created the original Tower of Pimps when messing with Ray's gold. Oddly enough, even though Gavin created the Tower of Pimps he himself has few wins under his belt. His house is a cobblestone art house with a secret trophy room inside the adjoining hill along with a hidden underground tunnel that connects his house with Michael's. Outside his house he has two picture frames with Creeper heads in them, as a Christmas gift from Geoff as a representation of his 'Creeper parents.' He also has a second Creeper head above his door frame and water melons lining the back roof of his house.
- Ray's character skin is the Tuxedo Steve skin, which he bases off of Tuxedo Mask from the anime, Sailor Moon. In going with the character, he is often seen carrying red roses in his inventory or close to his person. If another member does anything negative towards a rose, he displays violence towards them, such as Caleb, or will ensure the safety of a rose. He has displayed many other traits such as standing near a wall and admiring his face, pretending to masturbate, "shout out to...", creating signs with text humor, hatred for Cake, pointing out Endermen, and making karate related noises when ever the art picture is present. He often opens an episode shouting "LLLLLET'S PLAY!" which has become a staple for the series. His house was formerly a dirt house with a torch and dirt floor, which was later expanded to include a bed and a chest with Kung Fu related art work on his wall that hides Cake dispensers. He later added Pat the Head, which is a decorative Steve Mob Head, and an ocelot named Percival. He previously had a chicken named Conrad until it mysteriously disappeared. After Ray's departure from Achievement Hunter, his house was destroyed and replaced with a more extravagant house than his previous with its ownership being taken by Jeremy.
- Ryan's character skin is the Scottish Steve skin. Ryan joined in the Let's Plays shortly after joining Achievement Hunter, first appearing in Episode 24 - Capture the Tower! Ryan was originally only known as the "PC guy", but is now a full Achievement Hunter member and competes in Let's Play. Due to his PC knowledge, he normally helps with Geoff and Gavin when creating circuit related structures in Achievement City and leading of PC Minecraft Let's Plays. He is voice is often confused with Jack. Ryan has been seen to occasionally break the rules, although not always intentionally, and has become a staple for the rest to not to "pull a Ryan". Ryan claimed Kung-Fu House, what was formerly a storage house during the construction of Achievement City, as his house and has since made several additions to it, including a basement for his pet cow named Edgar. As of Episodes 217-219, Ryan's house has been replicated and relocated underground to bedrock as part of a prank against him. A railway connecting from the top of the hole to bottom circulates the outer walls surrounding his house. His house is no longer visible from above ground as the top was covered in dirt with a glass ceiling to view his house below.
- Caleb's character skin is usually the nurse skin, although he has also appeared with other skins, such as the Boxer Steve skin in Episode 28. Early on, Caleb usually appeared as a mediator and communicator between the creator of the community-made maps and the Achievement Hunter team; for example the Grifball map and the Labyrinth map. He has competed during Let's Play for the Tower but yet to win, and as a result of excessive cheating and screen-looking, he has been banned from the competitions. Screen-looking in the series is now usually referred to as "pulling a Caleb". His house is a simple 2x2x1 block hole, formerly filled with water. Caleb made a return in Let's Play Minecraft Episode 71.
- Jeremy's character skin is the Castaway, although he commonly wears a zombie head when he plays. He became a regular member of the cast in Episode 172 and moved into the newly renovated house, that was formerly Ray's, five episodes later in Episode 177. Before his promotion into the the main cast, he worked as a member of the Build Team and appeared in multiple Let's Builds.
- Lindsay first appeared as an aerial camera person in Episode 55: Creeper Soccer, she has since made several episode appearances either leading games, such as for Legends of the Hidden Temple, or competing. Lindsay also worked as a member of the Build Team and has appeared in multiple Let's Builds. She has the most character skin changes with three, her current one being Kazooie from Banjo Kazooie. Lindsay shares her house with her real life husband, Michael, where they have a double bed, and Kerry, who lives in a secret room below their house.
- Matt's unofficial first appearance was in Episode 18 as the map creator for Mineball. Several of his maps have been used in episodes, though he did not compete in them himself. Matt is not a typical player in competitions, acting as a majority of the time as a silent presence overseeing and filming the games. However, he has participated in multiple episodes with games and non, though he is one of the few to not have a house within Achievement City. Matt worked as a member of the Build Team where he appeared in multiple Let's Builds. Despite Let's Build's cancellation, he still acts as a primary builder of both structures and games, so much so that even Geoff and Gavin have been caught off guard by his secret builds. Matt's Minecraft skin is the Jack of Blades.
- Kerry appeared in Episode 74 due to Ryan being absent for personal reasons. He uses the Jetforce Gemini skin. Kerry was also in Episodes 89 and 90 as the assistant of Mad King Ryan. At the end of Mad King Ryan, Kerry became "Edgar" (dressed in a cow skin wearing diamond armor) and served as the final boss of the competition, which was won by Gavin. Kerry also made an appearance in Capture The Tower X during RTX 2014 playing as a Gent. His house is a hidden room underneath Michael's house which is connected to the Team Nice Dynamite tunnel.
- Kdin has appeared in multiple Let's Builds working as a former member of the Build Team. Kdin's character skin is the EnderDragon Man.
- Joel appeared once in Episode 2 and wore the Prisoner Steve skin. Joel did not partake in getting the achievement which was the goal of the Let's Play and left the group almost immediately. He was found by Gavin later in the episode and was killed, which led to him spawning back at the group house built by Ray. He assisted Michael in trying to stop Gavin from getting the "On A Rail" achievement but was unsuccessful.
- Mica has made one appearance thus far, in Episode 215 - Battle Mode. Her Minecraft skin is Aphrodite.
